Specification of Letters Patent.

1 Application filed June 3, 1914. Serial No. 842,754.

To all whom it may concern:

Be it known that I, HARRY S. MURRAY, citizen of the United States, residing at ltepublic, in the county of Fayette and State of Pennsylvania, have invented a new and usefulDevice for Watering Coke-Ovens, of which the following is a specification.

The invention relates to improvements in rotary watering devices for coke ovens.

The object of the present invention is to improve the construction of devices for Watering coke ovens and to provide a simple, inexpensive, and eflicient watering device of this character adapted to be readily made of cast metal and capable of reducing the friction and of permitting a free flow of water, whereby it is adapted to be operated with less water power than heretofore.

A further object of the invention is to provide an oven Watering device which will not require any adjustment and in which the parts will not present any sharp edges and be easy to assemble.

With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is aside elevation of a coke watering device constructed in accordance with this invention and shown applied to a coke oven, the latter being in section. Fig. 2 is an enlargedvertical sectional view of the watering device.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings, in which is illustrated the preferred embodiment of the invention, the rotary coke watering device, which is of a size to enable it to be introduced into the door opening 1 of a coke oven 2, comprises in its construction a relatively fixed casing 3, and a rotary spindle 4 carrying sprinkling arms 5. The casing and the spindle are designed to be constructed of cast iron or other suitable material, and the said casing, which is arranged vertically, is provided With a cylindrical opening 6 and has a bottom end wall 7 the upper end of the casing being open to receive the spindle l. The lower portion 8 of the casing is enlarged and is provided at one side with a threaded opening 9 for the reception of a horizontal pipe 10, which is connected with any suitable source of Water supply.

The rotary spindle, which is hollow, comprises a lower cylindrical portion 11, an intermediate portion 12, and an upper cylindrical portion or neck 13. The lower cylindrical portion extends into the casing 3 and the intermediate portion 12 is provided with an exterior annular flange 14, which caps the upper end of the casing. The casing is provided with horizontal upper bearing edges 15, and the flange 14 presents a fiat lower face to the same. The outwardly extending annular flange supports the hollow spindle and the wear is practically confined to this part of the device, as the lower cylindrical portion 11 of the spindle is of slightly less diameter than the interior of the casing, and terminates short of the bottom of the same at a point above the inlet opening. The upper portion or neck 13 is of less diameter than the lower cylindrical portion 11, and the intermediate portion 12 has an upwardly tapered interior 16 which connects the passages of the upper and lower portions of the spindle. The upper portion of the neck is provided with exterior screw threads 17, and has mounted on it a T- shaped coupling 18, in the opposite arms of which are secured the inner threaded terminals 19 of the sprinkling arms 5. The

sprinkling arms 5, which consist of pipes or tubes, extend from the upper end of the spindle and communicate with the passage thereof. The outer ends 20 of the sprinkling arms are threaded for the reception of closure caps 21. The water, which enters the casing at the bottom, passes freely through the hollow spindle into the sprinkling arms, which are provided at opposite sides with lateral discharge apertures 22, so that the water discharged from the device will rotate the spindle. The ends of the sprinkling arms are closed, and the water is discharged upon the supporting bed 23 of coke, which is sprinkled without wetting the walls of the coke oven and cansing the bricks thereof to chill and crumble.

Owing to the free How of water through the device, and the relatively small bearing portion of the hollow spindle, the device is adapted to be run with reduced pressure and is capable of thoroughly sprinkling a bed of coke more rapidly than heretofore.

What is claimed is 1. A rotary watering device comprising a casing adapted to be arranged upon the coke within a coke oven, said casing having a cylindrical interior and being open at the top, a hollow rotary spindle extending into and fitting the interior of the casing and provided with an exterior flange arranged upon the upper edge of the casing and capping the same, and sprinkling arms carried by the spindle and communicating therewith, said spindle terminating short of the bottom of the casing so that the weight of the spindle and the supporting arms will hold the exterior flange against the upper edges of the casing. v

2. A rotary Watering device comprising a vertical casing designed to be arranged upon the coke within a coke oven and having a cylindrical interior, said casing being open at the top and provided at the lower portion with an inlet opening, a hollow rotary spindle consisting of upper and lower cylindrical portions of different diameters and an intermediate portion having an upwardly tapered interior connecting the cylindrical portions, the lower cylindrical portion extending into and fitting the interior of the casing and terminating short of the inlet opening, and sprinkling arms connected with and carried by the upper cylindrical portion of the spindle, the latter having an exterior flange extending over the upper edges of the casing and supporting the weight of the spindle and the sprinkler arms.

In testimony, that I claim the foregoing as my own, I have hereto ai'lixed my signature in the presence of two witnesses.
